Decision Making #$1-$Sell or Process Further Joint Product Decision

XYZ manufactures A and B from a joint process cost $=$ $$60,000.$ Three thousand pounds of A can be sold at split$-$off for $$20$ per pound or processed further at an additional cost of $$11,000$ and then sold for $$25.$ Nine thousand pounds of B can be sold at split$-$off for $$14$ per pound or processed further at an additional cost of $$10,000$ and later sold for $$16.$

Requirements:

Which products should be processed further or not? Why? Give the total dollar impact to income for each product based on your recommendation. I am not looking for per unit information, but how each decision will impact the company's income in total

Decision making #$2-$Use of limited resources$-$singe constraint

Bush Manufacturing has $25,000$ labor hours available for producing M and N$.$ Consider the following information:

Required labor per unit in hours for M is $2$ and for N is $4$

Maximum demand in units for M is $9,000$ and for N is $6,000$

Contribution Margin unit for M is $$8$ and for N is $$15$

Requirements:

What is the optimal product mix$($how many M and N should be produced$)?$

You must provide the number of units to produce for each product at the optimal product mix and explain your answer along with supporting computations.
